Description
SBS (SeaBoss Systems) MULE Mk.I Light Services Truck

UPDATE: Heavy Duty Version Available -> https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=1913479647

First wheeled offering from SeaBoss Systems, the MULE is a Light Service Truck offering the following features:

- 6 Speed Automatic Gearbox: Select P, R, N, D by clicking on the 1x1 Gear Selection Monitor, press the Accelerator and the Vehicle will take care of the rest. There are additional options available from the Driver's seat to Lock the Current Gear, Force Gear Up and Force Gear Down. Locking the Current Gear disables the Auto Shift. It is useful for cases where you want to maintain a lower gear to allow for more torque while doing extreme hill climbs or towing.
- An additional Gearbox that can be kicked in when pulling, climbing or anything with higher torque is required. It is engaged from the Gearbox Mod Selection Monitor. Just click on the MOD rectangle and it will kick in the additional gearbox which modifies all of the existing gear configurations.
- Variable Accelerator (W) and Variable Brakes (S): the longer they are pushed the greater the speed increase or brake pressure
- Switchable between AWD (All Wheel Drive) and RWD (Rear Wheel Drive) on the fly. RWD offers more acceleration on roads while AWD offers more power when climbing or offroading. Defaults to AWD.
- Switchable between 2 Wheel and 4 Wheel Steering allowing for tighter turning. When 4 Wheel Steering is active you can also turn on an additional mode (Parallel) which alligns all of the wheels in the same direction. This allows the vehicle to move sideways.
- Interactive Map in front of Navigator's Seat
- Two Winches - One Located in the Front Hatch, One towards the Rear
- Two sets of Firefighting Gear in main cabin, one set of Arctic Gear located in Front Hatch
- Electric Tow Hitch (WIP, working on trailer options)
- Multi Mode Radio (Single Band, Two Way) available in main cabin
- Parking Brakes, Light Bar, Hazard Lights and Heater

CONTROLS:
- Turn Ignition Key to Start and Stop the Engine. There is an auto-starter which will kick back in if your revs should ever fall below 0.5 RPS. The MULE is set to maintain a minimum of 4 RPS to prevent stalling. If it goes below 4 it will disconnect the engine from the transmission.
- Press P, R, N or D on the Gear Mode Selection Window in front of the Drive to put the MULE in to its required mode. When Park is ON you can rev the engine with the accelerator but it will not change gear. When Neutral is on you can rev the engine and it will switch gears. Putting the Gear Mode back in to Park will always return the current Gear to 1.
- Press/Hold button W to Accelerate. The longer it is held the great the increase. You don't need to hold it to keep moving. Think of button W to be like a gas pedal on a car. You press it to get up to speed and apply pressure when needed to maintain.
- Press/Hold button S to brake. Same as above, the longer it is held the greater the pressure. Quick taps will slow you down slight. NOTE: the brakes are on on both the wheel and also the Engine. Pressing S will stop the wheels and tell the engine to slow down (throttle)
- Button 1 disengages the Wheels from the Drive Shaft when held (Push). If you find you are skidding/slipping disengaging the wheels will eliminate the excess torque from the engine temporarily allowing them to start rolling again. Think of Button 1 like a quick way to slam the gearbox in to Neutral.
- Button 2 locks the current Gear in place preventing it from Auto shifting up or down
- Button 3 forces the current Gear Up. Can be used in either Auto or Locked mode.
- Button 4 forces the current Gear Down. Can be used in either Auto or Locked mode
- There is a button near the map screen that toggles between AWD and RWD. AWD is on by default.

The MULE started off as an experiment relating to heat control, power and auto gearing using just a small engine and a single Radiator. It is capable of speeds exceeding 150 km/hour and should not break heat greater then 90 degrees when running full out. With the Drive Train there are 3 zones delineated by clutches: Engine, Transmission, Wheels. Each clutch is set in such a way that the pressure will ramp up depending upon the RPS of the zone. Additionally the
"Dependent Zone" will not be engaged until the "Power Zone" reaches the same RPS. For example. if the Transmission is rotating at 10 RPS and the Engine at 5 RPS the clutch between the Engine and the Transmission will not engage until the Engine reaches 10 RPS, if the Wheels are spinning at 15 RPS and the Transmission at 10 RPS, the clutch between the Transmission and the Wheels will not engage until the Transmission reaches 15 RPS. This allows for an amount of "coasting" preventing the Power Zone from reducing any current momentum in the Dependent Zone.

But I built this not to be conventional. 😉 It's an experiment in torque priority for a wheeled vehicle. It was a conscience decision. The vehicle is not geared for acceleration but for pulling and climbing power.

What you are describing is an electric drive train. That's what you actually want. Now with a gear/transmission drive train the only thing you are able to do is lose efficiency by adding parts, so therefore the trick is to use the bare minimum number of parts for the entire line, yeah it will end up being conventional bu that's exactly why the convention is what it is. ;)

In regards to the gearboxes I would have typically built it in the "multiplier mode" with multiple gearboxes values per gearbox. I chose to build it this way so that I could tinker with the gear setting on each transition. Additionally the extra gearboxes right now gives me the option of 6 gears, an additional 6 gears when the Modifier is applied and a separate reverse. It gives me lots of options for tweaking. It's packed tight but I wanted to also experiment with the numbers.

As for symmetry I'm fully aware of the tool. When placing wheels I usually turn it off.

Hello, agrimes. The vehicle has more then one clutch as I built it with a consideration that torque is going to drive the vehicle, not RPS. It was an experiment in not tying the vehicle to the RPS of the engine. This also gives us more pulling and climbing power. I separated the drive train in to 3 zones: Engine, Transmission and Wheels. When accelerating the clutch for each zone will not engage until the previous zone matches the same RPS. This allows the Transmission and wheels to be disengaged from the work of the engine getting up to RPS. This allows the vehicle to be driven like a "regular car": you only acclerate (apply torque) to maintain speed or increase speed, the subsequent zones should "coast".

on the little symmetry mode pull-out, the rightmost icon gives you a tool to move the symmetry plane around, I think that's what you were missing.
agrimes 4 Feb, 2020 @ 10:11am 
A nasty gotchya of this game is that many parts have a hidden mirrored version, so things like wheels must always be installed with symmetry mode active and on the left side of the vehicle. Doing this will cause the mirrored version to be placed on the opposite side of the vehicle. It's a very nasty and counterintuitive feature that affects engines too.

As for steering, I've started using a geometric curve to flatten the steering response, I have a 4WS module on my workshop that will implement the geometric curve and will work pretty well on any 2-axle vehicle without further tuning. https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=1892520382 Some vehicles are a bit more responsive on the rear end so you might have to tune the high response down to 0.5 or 0.6. Most vehicles will turn on a dime with this thing AND be controllable at speed with no other adjustments.

Overbuilt to the power of 100. =\ I think I had an older version from a mission pack... It's the densest design I ever tinkered with. Ok, it has some interesting features, I couldn't get the drivetrain touchscreen to work... Ok, I had already gone through and trimmed down/optimized removed a good number of the controllers. To start at the beginning, you absolutely cannot afford to waste any space on your drivetrain that isn't utterly essential. Mechanically speaking, this design needs to have EXACTLY one clutch. It also needs not more than three gearboxes. It needs the reversing box. Now for forward drive, a vehicle of this class only needs TWO gearboxes. Now think about it, each gearbox is controlled by one bit, so two gearboxes is two bits, and there are exactly 4 permutations of two bits, so therefore if you are crafty enough in choosing gear ratios, you now have a 4-speed transmission.

I appreciate you making this car. The changes are listed below. They should take you around 1 min to implement if you want to try it.
